3Health Administration Center, Japan Women'sUniversity Effects of ingestion of LS-cookies containinggalactosylsucrose (LS) were investigated on defecation, fecalcondition and microflora in 19 healthy female students, andcompared with those of placebo cookies or non-ingestion of anycookies. The subjects were given four pieces of placebo cookies(total 48g, without LS) daily for one week (control phase), and notfed any cookies for next one week (blank phase). Then they weregiven four pieces of LS-cookies (total 48g, LS 4g) daily for twoweeks. The fecal microflora were analyzed on the samples of 10subjects who were randomly selected from 19 subjects. The number ofdays with defecation per week was significantly increased by theingestion of LS-cookies as compared with the ingestion of placebocookies in the group (n=9) with the slight constipation(p<0.05). The effect of LS-cookies ingestion on defecationbecame remarkable in comparison with that of blank phase(p<0.05). Furthermore, the number of days with defecation perweek in all subjects was significantly increased by the ingestionof LS-cookies as compared with the blank phase (p<0.05),although the significant effect was not expressed in comparisonwith the control phase. Fecal conditions such as volume, color,shape and hardness feeling were significantly improved by theingestion of LS-cookies as compared with those of placebo cookies(p<0.05) and the non-ingestion (p<0.05). The ratio ofbeneficial microbes, Bifidobacteria, to anaerobes was increasedfrom 22.3% to 31% and the ratio of harmful microbes,Bacteroidaceae, was decreased from 42.6% to 32.2% by LS-cookiesingestion, respectively. These results demonstrate that theingestion of cookies (48g) containing galactosylsucrose (4g)increases the day with defecation per week, improves fecalcondition such as volume, color, shape and hardness feeling andpromotes the proliferation of beneficial intestinal microbes inadolescent females, in particular with slight constipation.
